I've been wanting to try these for a while, and our last very buggy trip to Yosemite pushed me to actually go for it. I used Wellness Mama's site for the recipe and just picked several essential oil combinations to try out.
I also blended up her recipe for Four Thieves Repellent which is currently sitting on my kitchen counter "marinating" for three weeks.
I really hope one of these repellents works, because I really hate that nasty smelling, itchy, chemical-laden stuff that we've had to use in the past. I will keep you posted on which essential oil combinations work the best for us.
